Equivalent Capacitance of a set of Capacitors

AI Thread Summary
The discussion focuses on calculating the equivalent capacitance of a set of capacitors using the formula for capacitors in series and parallel. The initial calculations show the equivalent capacitance for a combination of capacitors C1, C2, and C3, resulting in 3.42C. There is confusion regarding the series and parallel configurations of the capacitors, particularly with the combination of C2 and C3. The importance of distinguishing between series and parallel equations for capacitors is emphasized. Understanding these configurations is crucial for accurately determining the total capacitance in the circuit.

Homework Equations



1/Ceq= 1/C1 + 1/C2

The Attempt at a Solution



1/C13eq= 1/3C1 + 1/5C3 = 8C/3 = 2.67C

1/C12eq= (3C x C)/(3C + C) = 0.75C

Ceqtotal = 2.67C + 0.75C = 3.42C

I think the series circuit is throwing me off?

Consider the combination of C2 and C3 as a single capacitor in series with C1.

1/Ceq= 1/C1 + 1/C2


That's the equation for caps in series. What about the equation for caps in parallel?
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
